CHARLES A. LEFEVBE, or PONTIAC; MICHIGAN.

CAN-OPENER.

Specification of Letters Patent.

Application filed. Mareh 20, 1919. Serial No. 283,866.

To all whom it may concern:

Be it known that I, CHARLES A. LEFEVRE, a citizen of the United States,residing at Pontiac, county of Oakland, State of Michigan, have inventeda certain new and useful Improvement in Can-Openers, and declare thefollowing to be a full, clear, and exact description of the same, suchas will enable others skilled in the art to which it'pertains to makeand use the same, reference being had to the accompanying drawings,which form a part of this specification.

My invention relates to can openers and it consists in the arrangementand combinations hereinafter shown and specified in the claims.

In the drawings:

Figure 1 shows the device in position to detach the cover to a can.

Fig. 2 is a sectional view of the can and device showing it arranged inposition preparatory to opening the can.

Fig. 3 is a sectional drawing showing the device arranged in the closedposition upon the can cover.

Fig. 4 is a perspective view of the base of the device attached to thecover.

Fig. 5 is a perspective view of the connecting device.

Fig. 6 is a perspective view of that part of the device which engagesthe cover.

Similar letters refer to similar parts:

In the drawings A is the body of a can, B is the cover of the type whichis pressed into the can and having-a slight ledge C p which forms ashoulder which engages an internal ring D formed from the body of thecan. This is a usual and well known construction of can closures. Mydeviceconsists in attaching a plate of peculiar construction as shown inFig. 4 and marked E. This has a base F which is soldered to the cover Bwhen assembled. The end G is raised slightly and a bifurcated plate H isattached thereto either by soldering or any convenient method ofriveting or by fern ing it integral with the base. The bifurcated plateH carries a tongue J. Before attaching the plate F to the can cover, asstated, the parts are assembled by inserting the plate F into aperforated plate K through the slot L as shown in Fig. 1, the plate F isthen attached to the can cover in the manner specified. The perforatedplate 7 K contains another perforation M in which is hinged at N anothermember P. Punched out of the body of the member P is a tongue R, asshown in section in Fig. 2. In this figure the parts are shown in anoperative position. In Fig. 3 they are shown in a closed position. Thetongue J has a certain amount of resiliency and acts as a spring.

When the device is in operative position, as I shown in Figs. 1 and 2,the part P is turned over and the lip R having a slight resiliencyengages over the ledge C of the cover, then by lifting it in thedirection of the dotted line pulls the cover out of its closed position.

As assembled with the cover closed, as shown in Fig. 3, the part P isfolded back over the part K which is slid toward the center of the canover the plate F, the slot L permitting such movement until it passesunder the tongue J which by virtue of its elasticity holds the part P inposition, the tongue J passing through the opening S and under the lip Ras the part K carrying the part P is moved under the lip J. When neededfor use the perforated plate K is drawn outward disengaging the part Pin the position shown in Fig. 2, the part P is 'then drawn over the edgeof the can until the tongue R engages the edge of the cover C when thecover can be pulled out of place and the can thereby opened.

What I desire to claim is:

1. The combination of a cover of a can, a fixed plate F, a sliding plateK engaging therewith, a lever P hinged to the sliding plate K and havinga tongue adapted to en- Patented Dec. 9, 1919. i

gage the edge of the cover when in oper ative position.

a slot to engage the neck of said fixed plate when in another position,substantially as described.

3. In a can opener permanently attached to a can cover, the combinationof a plate fixed to the cover provided with a neck which carries aprojecting spring, a slidable member engaging said neck, a lever hingedto the, outer extremity of said slidable me1n her and adapted to foldback onto said slidable member, said lever being provided with a slot toengage the neck of said fixed member when folded back and to be held insuch folded position by the spring of said neck, a tongue carried bysaid lever adapted to engage the edge of the can cover when the lever isunfolded from said slidable member, substantially as described. 10

In testimony whereof I sign this specification.
